worlds fastest producton car, 1949 to present

from http://en.wikipedia.org/wiki/List_of_fastest_production_cars

It's odd to learn the fastest production car of any one year seems to be based on the 1/4 mile, or top speed, or 0 to 60... so to learn that the Aston Martin Vantage was faster than the best Ferrari that year is interesting, but may be based on just one statistic
